To all I'to/7mm t may con oef/v2. s

Be it known that l, Janine J.

a citizen of the United States, residing New vforli oity New Yoria haveinvente certain new and useful lmprov'emeni Journal Lubricators, oitwhich the f llo,.A ing is a lull, clear, and exact description, such aswill enable others skilled in 'the art to which it appertains to malteand u the same, reference being had to the accom aany ing` drawings,forming part ot this speciiication.

My invention relates to journal lubricators such as are used in railwayrolling stock) and consists in an improved lubricant reservoir and pumpconstruction adaptedto be applied to journal boxes and to be operated bythe relative movement between tbe axle journal and the journal box.

One of the objects or my invention is to provide a lubricator which maybe assembled with a standard `journal box without necessitating anyworlr on the latter.

An additional object is to utilize the bottom of the journal box for awall oit the lubricant reservoir, thereby reducing the amount ofmaterial required for the lubricator accessory.

An additional object is to provide a lubri- -cator which may be appliedto and removed from the journal box while the axlel journal is assembledtherewith.

A still further object is to so construct my lubricator that the journalbox may be jacked up while mounted on the journal to permit replacementof the brasses and wedges.

ln the accompanying drawings. which` illustrate a selected embodiment ofmy invention,

Figure l is a longitudinal vertical section through the lower portion ofa journal box with my lubricator applied and showing the axle journalassembled therewith.

Figure 2 is a transverse vertical section on line 2-2 of Figure l.

Figure 3 is a detail horizontal section ou line 3 3 of Figure l.

Figures 4 and 5 are similar to Figures l and 2 which show a modiicationor my invention.

rEhe lubricator body l consists preferably of a casting adapted to restupon the bottom of the journal box 2 and to extend upwardly toward theopening in the journal box and engage the inside wall of the latterSerial No. 501,869.

I to its openi i oer el is secured to not" i s d from the bottom of andextends oativanJ he side walls of the jourr" ,not between member anc.wall may be made oil-tight bj. merne ot p. c ing 5 or by a resilientpressure on the wall 2:'

indicated at The space between body i,

members fr, and the bottor journal box forms the lubricant reservoir.lntegral with body l is the pump cyl i der 7) open to the lubricantreservoir, disposed horizontally and provided with pump plunger 8 havinga curved :nsion 9 on its outer end. e lever l0 pivote the body l. enga t9, and projects be) ond body i. to a approximately opposite the axis ot7 assembled with the box. An ele pivoted to the outer end of lever isadapted to engage center hole 152 in the journal and to transmitshitting moveli) and ment or' the journal in one direction tlirouifi 80lever l() and extension 9 to )lunemx Movement or plunger 8 in trie opprection is provided by a spring pressed between shoulder at tl'ic o" crend of cylinder 7 and an opposing shoulder 85 on the plunger.

rlhe pivoting of element ll on lever l() permits relative vertical moveent oitl the journal and the journal box w. ut effecting the lubricator.j l prefer to m e element llso that in emergency it will yield to tlm.shifting movement ol the journal to prevu, injury to the pump mechanism.A'

The intake to cylinder ).7 is provided with a suitable check valveleland the discharge from cylinder Z is through a passage in upwardlyextending lug l5 which is provided with a check valve lo, Telescopicallymounted in lug l5 is bushing 17 adapted to bear against the bottoni ofthe journal irrespective of the vertical position of the latter. Aspring 18 compressed between the valves 16 and suitable tongues onbushing 17 serves at once to press both bushing and valve to theirdesired positions.

lt will be noted that the lubricator has no bottom and cooperates withthe bottom of the journal box to form the lubricant reservoir. Thisconstruction provides a comparatively shallow lubricator which permitsthe journal box to be jacked up in the usual manner when it is journalbrass ll-Jhen this operation is performed, the supporti-ng portion i? ofthe body l land the top or lug l5 engage the bottom of the journal boxand the axle journal, respectively, to li` it. the movement or thejournal and box toward each other and prevent injury to the lubricator.

lil/vaste may be packed over the top ofi the lubricator in the usualmanner and the construction is such that the car maybe reversed on adumping machine without loss of oil, which is an advantage not presentin many types oit lubricators.

ln the modilication 'shown inliigures 4: and 5, the pump cylinder 19 andhousing 20 is lormed integral with the journal box and the pump plunger2l, is operated by means el a rock and gears and 2a. The latter arejournaled in housing 20 and are driven alternately in oppositedirections by a segment gear forming one end of a lever 26 which isfulcrumed in the upper end of l'iousing` and is reciprocated by thecontact or elementv 2i' with the eno or the axle journal. rlhe upperlace of housing 2O is slotted at 2,9 to permit the insertion of gears 23and 2li and of the segment gear 25. A waste holder 28 is mounted on thejournal boX and on housing 20 similarly to the Waste holder 4 shown inthe preferred construction. A

rlhe principle oic operation of this mod-ilication is the same as thatof the preferred construction and the essential features of Vthe latterare retained.

@ther changes in the construction of my device may be made, Withoutdeparting from the spirit ol the invention, as set 'forth in thefollowing claims.

l claim:

l. ln combination, a railway axle journal, a standard journal boxcarried thereby, a member cooperating with thebottom of said box to forma closed lubricant reservoir, a

`telescoping passage leading from the reservoir formed to said journaland adapted `to accommodate variations in the vertical position out saidjournal, and a pump operated :learner by relative `'nerirental movementor said boi; and journal '(ior feeding lubricant Uhrough ,said passage.

2. in a lubricator, a body member adapted to be positioned on the bottomor' a. standard railway journal box to form a lubricant reservoir', adownwardly extending support on said member, an `upvrardly extending lugon said member adapted to limit upward movement, relative to a journal,or said body. and a journal bor; assembled therewith, a bushingtelescopieally mounted in said lug, and lubricant passage from saidreservoir to said lug and bush-ing'.

3. ln a journal lubrioator,a lubricant reservoir, a pump cylinder 4openthereto, a pump plunger reeiprocally mounted in said cylinder andextendingoutwardly therefrom into saidreservoir, a spring compressedbetween the end or saidlcylinder and the outwardly extending` portion ofsaid plunger, and a member extending outside off said reservoir andadapted to be operated by movement of a journal relative fto Vthereservoirk forjoperating said plu-nger to compress said spring. l

4i. In a journal box, `a lubricant reservoir, a pumping mechanism, andarigid element adapted to be supported upon the bottom of a journal boxand 4extending above said reservoir, whereby 'when fthe journal box visjacked up relatiif'etoa journal with .Which `it is assembled, saidelement will engage the journal and prevent injury to said Ireservoir`and pumping mechanism.

5. ln a journal lubricator, a `luliricant reservoir, a pump cylinder, adischarge :passage therefrom, a check valve in :said passage, atelescoping` extension oi said @passage adapted to contact With-the`suriaceiof a journal to be lubricated, and aspring compressed betweensaid check valve and extension to press the valve toward its seat andthe eir- 'tension toward its-projected position.

ln testimony whereof l hereunto aizr my signature this 29th day of June, 1921.
